Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Percentage of Participants With Human Immunodeficiency Virus -1 Ribonucleic Acid (HIV-1 RNA) <50 Copies/mL
Time Frame: Baseline (Week 0), Weeks 4, 12, 24, 36, 48, 60, 72, 84, 96, 108, 120, 132, 144
Viral load (number of HIV-1 RNA copies in the blood) was measured at baseline and scheduled study visits. A decrease in viral load is a measure used to assess the effectiveness of antiviral treatments. The percentage of participants with HIV RNA less than 50 copies/mL at each time point is presented.
Baseline (Week 0), Weeks 4, 12, 24, 36, 48, 60, 72, 84, 96, 108, 120, 132, 144

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change From Baseline in Absolute CD4 Cell Count
Time Frame: Baseline (Week 0), Weeks 4, 12, 24, 36, 48, 60, 72, 84, 96, 108, 120, 132, 144
Increases in CD4 count are a biomarker for antiretroviral treatment effectiveness in restoring immunologic function. Changes in participants' CD4-positive (CD4+) T-lymphocyte counts were assessed by measuring the change from Baseline in the number of CD4+ cells at scheduled study visits.
Baseline (Week 0), Weeks 4, 12, 24, 36, 48, 60, 72, 84, 96, 108, 120, 132, 144

Time Frame: Baseline (Week 0), Weeks 4, 12, 24, 36, 48, 60, 72, 84, 96, 108, 120, 132, 144
Increases in relative CD4 count (the percentage of total lymphocytes that are CD4 cells) are a biomarker for antiretroviral treatment effectiveness in restoring immunologic function. Changes in participants' CD4-positive (CD4+) T-lymphocyte counts were assessed by measuring the change from Baseline in the percentage of CD4+ cells at scheduled study visits.
Baseline (Week 0), Weeks 4, 12, 24, 36, 48, 60, 72, 84, 96, 108, 120, 132, 144

Time Frame: Baseline (Week 0), Weeks 4, 12, 24, 36, 48, 60, 72, 84, 96, 108, 120, 132, 144
Decreases in CD8 count are a biomarker for antiretroviral treatment effectiveness in restoring immunologic function. Changes in participants' CD8-positive (CD8+) T-lymphocyte counts were assessed by measuring the change from Baseline in the number of CD8+ cells at scheduled study visits.
Baseline (Week 0), Weeks 4, 12, 24, 36, 48, 60, 72, 84, 96, 108, 120, 132, 144
Change From Baseline in Relative CD8 Cell Count
Time Frame: Baseline (Week 0), Weeks 4, 12, 24, 36, 48, 60, 72, 84, 96, 108, 120, 132, 144
Decreases in relative CD8 count (the percentage of total lymphocytes that are CD8 cells) are a biomarker for antiretroviral treatment effectiveness in restoring immunologic function. Changes in participants' CD8-positive (CD8+) T-lymphocyte counts were assessed by measuring the change from Baseline in the percentage of CD8+ cells at scheduled study visits.
Baseline (Week 0), Weeks 4, 12, 24, 36, 48, 60, 72, 84, 96, 108, 120, 132, 144
Change From Baseline in CD4/CD8 T-cell Ratio
Time Frame: Baseline (Week 0), Weeks 4, 12, 24, 36, 48, 60, 72, 84, 96, 108, 120, 132, 144
The CD4/CD8 T-cell ratio, also known as the T-lymphocyte helper/suppressor profile, presents the number of lymphocytes in the blood positive for CD4 cells compared with the number positive for CD8 cells. Changes in participants' CD4/CD8 T-lymphocyte ratio were assessed by measuring the change from Baseline in the ratio at scheduled study visits.
Baseline (Week 0), Weeks 4, 12, 24, 36, 48, 60, 72, 84, 96, 108, 120, 132, 144
